Text Solution

Verified by Experts

The correct Answer is:
A
Since adsorption is an exothermic process (taking place with the evolution of heat) therefore, in accordance with Le-Chatelier's principle, the magnitude of physical adsorption will decrease with the increse in temperture. In case of chemisorption the adsorption first increased and then decreases. with incerease in temperature.
